Introduction

This document will guide you through installing the Intel® Atom™ x86 image for Android* Jelly Bean, which can be used for development on Intel’s x86 architecture.

Prerequisites

The Android x86 Emulator Image requires the Android SDK to be installed. For instructions on installing and configuring the Android SDK, refer to the Android developer website (http://developer.android.com/sdk/).

Optional: The x86 Emulator Image for Android can be accelerated using Intel Hardware Accelerated Execution Manager (HAXM). For more information, refer to the "Optimization" section of this document.

Known Issues:

Caffeinemark may have issues and logcat may indicate a crash at ashmem/libdvm

Video clips played in the browser only have audio and no video. This only occurs in the browser and not when played back full screen.

Screen capture is not working with ddms, uiautomatorviewer or monkeylmage

Snapshot feature is not working

Factory data reset is not working

Camera application crashes from the start if none is set to the front and rear camera

Extract the x86 directory contained in the downloaded system image archive directly into the android-18 directory. The directory “./Android-SDK/system-images/android-18/x86/” should have the following files:

The system image is now installed and ready to be used.

Mac OSX

Navigate to the directory where you extracted the SDK

The system-images directory contains Android system images, separated by architecture: If a “system-images” directory or an "android-18" directory does not exist then you will need to create it / them.

Extract the x86 directory contained in the downloaded system image archive directly into the android-18 directory. The directory “./android-sdk-macosx/system-images/android-18/x86/” should have the following files:

The system image is now installed and ready to be used.

Using the System Image

Start the Android AVD Manager and create a new AVD, setting "Target" to "Android 4.3 – API Level 18", and "CPU/ABI" to "Intel Atom (x86)".
The Intel Atom x86 Image for Android Jelly Bean can make use of hardware GPU features to increase the performance of games, graphics-intensive programs, and user interface elements. For the best performance make sure to check the "Use Host GPU" Box when creating the image.Note: The functionality and performance of GPU acceleration is highly dependent on your computer’s graphics card and graphics drivers. GPU acceleration must be enabled on a per AVD basis.Note: if the "Intel Atom (x86)" CPU/ABI option is not available, make sure that the system image is installed correctly. You can confirm the system image installation by opening the Android SDK manger and looking at the status of the “Intel x86 Atom System Image” under “Android 4.3 (API 18)”

Click the "Create AVD" button.

The AVD has been successfully created and is now ready to use:

Optimization

CPU Acceleration

The performance of the Intel Atom x86 Image for Android Jelly Bean can be improved with hardware-based virtualization using Intel VT-x technology.

If your computer has an Intel processor with VT-x support, it is recommended that Intel Hardware Acceleration Execution Manager (HAXM) be used in conjunction with this system image. For more information about Intel HAXM, visit http://www.intel.com/software/android.

Note: Intel HAXM is for Windows and OS X operating systems only. For Linux hosts, Kernel-based Virtual Machine (KVM) can be used to accelerate emulation performance. For information on installing and configuring KVM on Ubuntu, refer to this guide:https://help.ubuntu.com/community/KVM/Installation
